I think we dream so that we don't have to be apart for so long...
Apart from our goals, and our dreams themselves? Maybe. Apart from loved ones, most definitely. The so called "few" people that have the guts to follow their dreams deserve to be called heroes, for not only have they the guts, but the persistence and the stregnth, both moral and physical, and, on top of it all, the most important possession in the universe: they have a Soul.
